respectively on shafts 37, 38 and 39, the gear 41 mesh- '43 with a sprocket 45 fixed on main drive shaft 23.

Thus shafts 37, 38 and 39 are driven in timed relationship with main drive shaft 23.

Mounted on the shaft 37 over the path of. the grids 16 is a pick-up cylinder 46, and fixed on shafts 38 and 39 adjacent the cylinder 46 are cylindrical delivery As shown more clearly in Figs.'4 and 7 to 9, delivery roller 47 is positioned below the delivery roller 48. The cylinder 46 and de livery roller 48 are formed with similar spaced annular :peripheral grooves for receiving a pair of endless coil spring belts 49. As shown in Figs. 7 to 9, the belts 49 engage the periphery of the lower delivery roller 47, and also engage pick-up cylinder 46 and upper delivery roller 48 in the belt receiving grooves thereof. Mounted adjacent the delivery roller 47, above plate 21 and above the path of the grids 16, is a horizontal plate 50 forming a receiving table. The plate 50 is formed with a rectangular notch 50' as shown in Figs. 1 to 3. Referring to Fig. 1, the cone forming machine 17 has a cake receiving portion 17' which is positionable in substantially the same horizontal plane as the upper surface of the receiving table 50.

Referring to Figs. and 6, the cylinder 46 is formed with a central cavity 51 which is closed by a semicircular shell 52, the latter being held in place by screws 53. A shaft 54 is rotatably mounted in the cylinder 46 parallel to the shaft 37 and ofiset radially therefrom. shaft 54 extending through the cavity 51 as shown in Fig. 6. An arm 55 is fixed to the shaft 54 within cavity 51, and arcuate pins 56, preferably three in number,

are fixed to the arm 55. The shell 52 is formed with a slot 57 for each of the pins 56. The pins 56 can be withdrawn into the cavity 51 and within the periphery of cylinder 46 to the dot and dash line position of Fig. 6

by rotation of the shaft 54 in a clockwise direction as ,viewed in said figure. The shaft 54 extends toward the bearing 34 and exteriorly of the cylinder 46. A crank arm 58 is fixed to the projecting end of said shaft, said arm carrying an eccentric shaft 59 on which a cam following roller 60 is mounted.

Fixedly mounted adjacent the bearing 34 and coaxial ,with the shaft 37 is a sleeve 61, into the open end of j which the roller 60 projects. Mounted within the sleeve 61 are adjustable arcuate cam segments 62 and 63, which; t

;are positioned for engagement by the roller 60. The 1 I sleeve 61 is slotted, as at 64 and 65, to receive adjustment screws 66 and 67, which screws are threaded into :the segments 62 and 63 respectively to lock the latter -in a selected position. As shown in Fig. 6, the cam segments 62 and 63 overlap at one end and are spaced from one another at the other end. The cam following roller engages the inner surfaces of the cam segments 62 and 63 as the cylinder 46 rotates, and when said follower moves into the area between the spaced ends of the cam segments, said roller moves radially outwardly to engage the inner surface of the sleeve 61. While the roller 60 is in engagement with the inner surface of the 16 on supportlng ring 15 is synchronized with the rotation of shaft 37 and cylinder 46. The cam segments 62 j and 63 are so positioned and the timing of the roller 46 with respect to the grids 16 is such, that when the leading edge of a cake 68 reaches the position under the cylinder 46 shown in Fig. 7, pins 56 are projected .fllrough the slots 57 and piercingly engage a leading edge portion of the cake 68, peeling said cake from grids 16 and feeding the leading edge portion of said cake to the nip between belts 49 and roller 47 as shown in Fig. 8.

At this point, cam segment 62 is engaged by the follower 60 and the pins 56 are withdrawn into the slots 57, thereby stripping themselves from the cake 69 as shown in Fig. 8. As the cylinder 46, belts 49 and rollers and 48'continue'to rotate, the cake 68 is delivered onto'thereceiving table 50 as shown in Fig. 9. At the same time the supporting ring 15 continues to rotate, and by the time the leading edge portion of the cake on the succeeding grid 16 is positioned under the cylinder 46, the pins 56 are again projected as shown in Fig. 7 to repeat the pickup operation. In Fig. 1, a cake 68 is shown on the receiving table 50, and another cake 68 is shown with its leading edge portion moving under the pickup cylinder 46.

Referring now to Figs. 1 to 3, a bearing sleeve 69 depends from the outer end of the arm 33, and rotatably mounted in said sleeve is a shaft 70. A pulley 71 is fixed to the shaft above the arm 33, and a plate 72 is fixed to the lower end of the shaft 70. The plate 72 is generally L-shaped as shown in Fig. 1, having an arm 73 and an arm 74, both extending in substantially the same horizontal plane as the receiving table 50, as shown in Figs. 2 and 3. The arm 74 is formed with upstanding spaced ears 75 and 76, which are bored to receive a pin 77. Fixed on the pin 77 between the cars 75 and 76 is a plate 78 forming an upper jaw which is complementary to the arm 74 and positioned thereabove. A generally U- shaped torsion spring 79 has its end portions fixed in suitable apertures in the lugs 75 and 76, and the central portion of said spring engages the upper surface of the jaw '78 in a manner to urge the latter downwardly. Fixed to the pin 77 outwardly of the lug 75 is an arm 80 which carries a roller 81 at its outer end. A similar arm 82 having a roller 83 is fixed on the other end of. the pin 77 outwardly of ear 76.

A coiled tension spring 84 is fixed at one end to the periphery of the pulley 71 and extends around said pulley and has its other end fixed to arm 83 as at 85. Depending from the outer end of arm 73 of plate 72 is a shaft 86 on which a cylindrical roller 87 is rotatably mounted (see Figs. 2 and 3). The table 21 is formed with an arcuate slot 88 in which the roller 87 is slidably positioned. One end of the slot 88 is positioned adjacent the receiving table 54 and the other end is positioned adjacent the cone forming machine 17. Slot 88 diminishes in radius, with respect to the axis of shaft 31, from its left hand end to its right hand end as shown in Fig. 1. The plate 72 and the parts mounted thereon constitute a gripper mechanism, and when the arm 33 is positioned as shown in Fig. 1, the jaws 74 and 78 are positioned in the notch 51 of the receiving table 50. When the arm 33 swings toward the dot and dash line position of Fig. 1. roller 87 traveling in slot 88 causes clockwise rotation of plate 72, so that when the arm 33 reaches said dot and dash line position, the arm 74 of plate 72 is pointed at the cake receiving portion 17 of the cone forming machine.

Mounted on plate 21 adjacent to receiving table 50 and to one end of slot 88 is an upstanding bar 89 having a transverse arm 90 mounted on its upper end and extending inwardly over the slot 88. A cam member 91 is pivotally mounted on the inner end of the arm 90 in the path of movement of the roller 81. An L-shaped stop member 92 is fixed to the bar 89 and extends transversely inwardly to limit the pivotal movement of cam 91 in a clockwise direction as viewed in Figs. 2 and 3.

Adjacent the cone forming machine 17 and mounted on plate 21 is an angle member 93 having an upstanding flange 94, to which flange an angle member 95 is fixed, the latter having a horizontal flange 96 spaced above plate 21. The flange 96 is positioned for engagement by the roller 83 when the gripper is in the dot and dash line position of Fig. 1.

In the operation of the cake transferring mechanism, assuming that the arm 33 is positioned intermediate its arc of swinging movement, and is moved toward the receiving table 50 as a cake 68 is being deposited on said table, the gripper mechanism moves to the position of Fig. 3. In this position the roller 81 has moved under the cam 91 and is depressed thereby, rotating pin 77 and lifting jaw 78 as shown. Jaws 74 and 78 are now pointed into the notch 50' of receiving table 50, and jaw 74 is moving under the cake 68 while the jaw 78 simultaneously moves thereover. As the arm 33 continues to swing toward the limit of its travel, roller 81 moves out of contact with cam 91, and spring 79 snaps jaw 78 down onto cake 68 to firmly grip the latter as shown in Fig.2.

Arm 33 is immediately swung in the reverse direction toward the dot and dash line position of Fig. 1, the cake 68 being transferred from the receiving table 50 to the dot:and-dashzlineapositionvvhere antedgegportiontofssaid cake is received in the cakerreceivingg-portion t1 'adf one of :the movable, conical forming units of ithe acak'erform- =ing machine 17 by-means *or *which the cakefisrmoved otf of the plate 21. lnasmuchias the unit 17 iszof a type ;well *known and-forms no zpart of atherpresent invention, :it iisnot being described in 'detail herein. :As the arm -33 approaches the dot and 'dash line ,;position xof @Fig. :1, roller 83 -engagesthe fian'ge 96 andnisdepressedntherebyito lift the jaw 78 and release the cake otiws flIe latter-is =dravvn intoltheicake forming machined-7.
